Title:
METHOD, SYSTEM, AND COMPUTER-READABLE MEDIUM FOR GENERATING SPOOFED STRUCTURED LIGHT ILLUMINATED FACE
Document Type and Number:
WIPO Patent Application WO/2020/057365
Kind Code:
A1
Abstract:
In an embodiment, a method includes determining a spatial illumination distribution using a first image caused by at least first structured light and a second image caused by at least second structured light, wherein a portion of the first image is caused by a portion of the at least first structured light traveling a first distance, a portion of the second image is caused by a portion of the at least second structured light traveling a second distance, the portion of the first image and the portion of the second image cause a same portion of the spatial illumination distribution, and the first distance is different from the second distance; building a first 3D face model; rendering the first 3D face model using the spatial illumination distribution, to generate a first rendered 3D face model; and displaying the first rendered 3D face model to a first camera.
